Hagner Model EC1-X IR Digital Radiometer
The EC1-X IR has been designed for measurement of radiation levels in places where it is important
that the operator does not shade the detector. The EC1-X IR has the detector connected with a 2
meter long cable. An extension cable can also be connected.
The Hagner Digital Radiometer, model EC1-X IR, is a small, handy and easy-to-use instrument for
accurate measurement of radiation over a range of 0.01-20,000 W/m². With both automatic zeroing
and on/off switch, the only controls needed are a four-position range selection switch and a hold
button for retaining the display value.
Operation
The EC1-X IR is used exactly as the EC1. The detector can be connected or disconnected without
causing any damage to the instrument. Care should be taken to ensure that the cable is not twisted
when replacing the cable. It is recommended that the detector is rotated rather than winding the
cable around the detector.
To open the lid, press the forward part lightly downward with your thumb and at the same time pull
the latch upwards with the first two fingers of the same hand. The radiometer comes on when the
cover is opened and turns off when it is closed. Move the range switch to the range which will give
the greatest accuracy and read the display. The hold function keeps the reading on the display until
the hold button is released. Full instructions can be found on the inside of the cover.
